Maximum Pulse Frequency Of The Incremental Encoder - WAGO -I/O-SYSTEM 750 Manual

2.1.1.9.12

Maximum Pulse Frequency of the Incremental Encoder

Common 24 V DC collector motors normally have a maximum revolution
speed of approximately 4,600 min
1 ... 10,000 pulses/rev max. The module's encoder inputs can capture a
maximum of 50,000 pulses per second.
Assuming a revolution speed of 4,600 min
incremental encoder should provide a maximum of 652 pulses/rev. Encoders
with 512 pulses per second normally meet the requirements of DC motor
applications.
The following diagram illustrates the connection between revolution speed
and the maximum admissible number of pulses/rev of the incremental
encoder.
To avoid overloading the quadrature decoder/counter, it is essential for the
incremental encoder to function below the maximum value for pulses/rev.
